“…Before the 1990s maps, other than of the soil and possibly landscape, played little part in agricultural management. Schafer et al (1984) stated that maps of soil type and topography could be used to control fertilizer and pesticide applications and tillage operations. The first yield map of Searcy et al (1989) showed the effect of compaction from farm machinery on yield (see Oliver, 2010).…”

Precision agriculture (PA) involves the application of technologies and agronomic principles to manage spatial and temporal variation associated with all aspects of agricultural production in order to improve crop performance and environmental quality. The focus of this book is to introduce for a nonspecialist audience the role of PA in food security, environmental protection, and sustainable use of natural resources, as well as its economic benefits.The technologies covered include yield monitors and remote sensing, and the key agronomic principles addressed are the optimal delivery of fertilizers, water and pesticides to crops only when and where these are required. As a result, it is shown that both food production and resource efficiency can be maximized, without waste or damage to the environment, such as can occur from excessive fertilizer or pesticide applications. The authors of necessity describe some technicalities about PA, but the overall aim is to introduce readers who are unfamiliar with PA to this very broad subject and to demonstrate the potential impact of PA on the environment and economy.The book shows how farmers can place sustainability of the environment at the centre of their operations and that this is improved with the application of PA. The range of topics described includes sampling and mapping, weed and pest control, proximal and remote sensing, spatio-temporal analysis for improving management, management zones and water management.

“…They also provide pathways for the movement of wheels of farm machinery and draft animals. In practice the system works much like a controlled traffic tillage reported to be advantageous at other places ( Schafer et al, 1981 ). The compaction due to the movement of wheels and oxen is restricted to the noncropped zone, and the cultivated area remains relatively friable ( Klaij, 1983 ).…”

Efficient utilization of energy with an improved farming system for selected semi-arid tropics. Agric. Ecosystems Environ., 24: 381-394. The International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), India, has developed an improved technology for the management of Vertisols. The results of testing of this technology in farmers' fields in India have shown that substantially higher yields can be achieved by an efficient application of available energy resources along with other high-value inputs. The technology does not depend upon a tractorized form of energy and improves the productivity of farm labor.

“…Two incorporation passes are commonly used to improve the uniformity of herbicide incorporation (Schafer et al, 1984). Single pass incorporation can result in non-uniform placement of the herbicide (Thompson et al, 1981), causing streaked weed control.…”

A procedure using computer vision and fluorescent dye was developed to determine the incorporation characteristics of tillage tools. It was assumed that the fluorescent dye represented herbicide and would be displaced in a similar manner as herbicide applied to the soil. Image processing was used to store and analyze the incorporation profiles. The Kolmogorov-Smirnov statistical test was used to quantitatively compare incorporation profiles. The procedure was very quick and accurate.
